What are the 4 major groups of protozoa?

Historically protozoa were divided into four major groups: the ameba, the flagellates, the ciliates, and the sporozoa. The distinguishing features between the groups was based on motility (i.e., ameboid, flagella, cilia).

Malaria is caused by protozoa of the genus Plasmodium. Four species cause disease in humans: P falciparum, P vivax, P ovale and P malariae. Other species of plasmodia infect reptiles, birds and other mammals. Malaria is spread to humans by the bite of female mosquitoes of the genus Anopheles.

What are the 4 different ways that protozoa move?

Explanation: The members the protozoa move by cell extension, flagella, pseudopodia and cilia. The method of movement is determined by the type of organism and their environment. Ciliates move using tiny cilia, flagellates move using flagella and amoeba by crawl along surfaces by extending pseudopodia.

Giardia (/dʒiːˈɑːrdiə/ or /ˈdʒɑːrdiə/) is a genus of anaerobic flagellated protozoan parasites of the phylum Metamonada that colonise and reproduce in the small intestines of several vertebrates, causing giardiasis. Their life cycle alternates between a swimming trophozoite and an infective, resistant cyst.
